The CDC Foundation, which supports the US Centers for Disease Control and Prevention, has put up a new publication urging business travelers to protect their health when they travel internationally and steering them to resources to help.

It’s a smart idea backed by some eye-opening statistics:

Cost of a course of malaria prophylaxis drugs: $162. Cost of being hospitalized with malaria on return: $25,250.

Cost of taking the two-dose hepatitis A vaccine: $300. Cost of treatment for a case of hep A: $2,500.

Cost of medical evacuation insurance: $370. Cost of a medical emergency evacuation: up to $250,000.
